If you're willing to test your health and nutrition knowledge against some science, the Fix or Fraud quiz is a fun way to learn—or teach—some basic food and nutrition tips while simultaneously dispelling a number of long-held superstitions and placebos that still get passed around.

The quiz is meant to be in good fun, and while there are only ten questions, I admit even I screwed up on a few the first time I took the quiz. Each verdict is presented with the source study that supports it at the bottom of the page (you'll have to click "source" to see it) so you can read the research that helped get to the conclusion. Some of the questions, like whether aloe heals cuts and burns, coconut oil helps you lose weight, or whether cranberry juice really does help with urinary tract infections, can be quite contentious, so no one's expecting a single study to settle the issue (and it may be just as easy to find another source that pokes holes in the yes/no answer), but it is good to get an idea of what research says on the topic and what statements are designed to sell you products, diets, or supplements.
